Embodiment
Below in conjunction with the accompanying drawings and the specific embodiments press-key structure of the present invention and the electronic installation with this press-key structure are described in further detail.
Refer to Fig. 1 and Fig. 2, electronic installation 100 comprises that various functional module group are for realizing various corresponding functions, yet for saving space, the present embodiment introduces the housing 101 of this electronic installation 100 and is fixed on the press-key structure 103 on housing 101.Specifically in the present embodiment, press-key structure 103 is the menu button of electronic installation 100, the shell that housing 101 is electronic installation.On housing 101, offer containing hole 102.
Press-key structure 103 comprises keycap 10, fixed support 20, strutting piece 30, key switch 50 and elastic component 60 and fixture 70.Button cap 10 parts are contained in the containing hole 102 of housing 101.Fixed support 20 is fixed on the medial surface of housing 101, and arranges near containing hole 102.Strutting piece 30 is fixedly connected with fixed support 20, and is oppositely arranged with containing hole 102.Key switch 50 is fixed on strutting piece 30.Elastic component 60 is rotationally connected with keycap 10 and fixture 70.Fixture is fixedly connected with strutting piece 30.
Keycap 10 comprises a press section 11, limiting section 13 and two connecting portions 15.Press section 11 is roughly rectangular ellipse, and it can slide in the containing hole 102 of housing 101.Limiting section 13 is located at a side of press section 11.The size of limiting section 13 is greater than the size of the containing hole 102 of housing 101, to prevent that press section 11 from coming off from containing hole 102.Two connecting portions 15 are located at respectively the two ends of the outer surface of limiting section 13.In the present embodiment, the breach 152 that offers axis hole 151 and be connected with axis hole 151 of each connecting portion 15.
Fixed support 20 comprises first fixed part 21, two the second fixed parts 23 and the 3rd fixed parts 25.The first fixed part 21 is rectangle plate body, and it is fixed on the inner side of housing 101.Two the second fixed parts 23 extend from the two ends bending of the first fixed part 21 1 sides respectively.The two ends of the 3rd fixed part 25 are connected with two the second fixed parts 23 respectively.The first fixed part 21, two the second fixed parts 23 and the common framework that forms a ring-type of the 3rd fixed part 25.In the present embodiment, the first fixed part 21 adopts the mode of welding to be fixed on the inner side of housing 101.The 3rd fixed part 25 is for being fixedly connected with other element (not shown) of electronic installation 100.
Strutting piece 30 comprises body 31 and is located at the support portion 32 at the middle part of body 31 1 sides.Body 31 two ends offer respectively a through hole 312.Body 31 wears on the second fixed part 23 that through hole 312 is fixed on fixed support 20 by screw (do not indicate).
Fixture 70 comprises fixed part 71, be located at two the first grabs 72 and the second grab 73 on fixed part 71.In the present embodiment, fixture 70 is one-body molded by elastomeric material.
Please refer to Fig. 2 to Fig. 4, during assembling press-key structure 103, first the middle part of the rotation section of elastic component 60 61 is snapped in the second grab 73 of fixture 70, two sides of rotation section 61 snap in respectively in the first grab 72 of fixture 70.Two ends of elastic component 60 are snapped in axis hole 151 from the breach 152 of two connecting portions 15 of keycap 10 respectively, make the relative keycap 10 of elastic component 60 rotatable.The press section of keycap 10 11 is contained in the containing hole 102 of housing 101.The first fixed part 21 of fixed support 20 is fixed on to the inner side of housing 101.The two ends of the body of strutting piece 30 31 are fixedly connected with two the second fixed parts 23 of fixed support 20.Key switch 50 is fixed on to a side of strutting piece 30, and the fixed part of fixture 70 71 is fixed on strutting piece 30.Under the state not triggering at key switch 50, the rotation section of elastic component 60 is equivalent to fixture 70 and has rotated certain angle, make resiliency supported portion 62 owing to compressing mutually elastic deformation occurs with strutting piece 30, provide an elastic-restoring force in the rotation section 61 of elastic component 60, thereby make the limiting section 13 of keycap 10 and trigger unit 51 close contacts of key switch 50.
While using press-key structure 103, the press section 11 of pressing keycap 10, makes keycap 10 slide towards the trigger unit 51 of key switch 50, until trigger key switch 50.Deformation recovers completely in the resiliency supported portion 62 of elastic component 60 or elastic module reduces.While unclamping the press section 11 of keycap 10, the trigger unit 51 of key switch 50 automatically resets and jack-up keycap 10, making the rotation section 61 of elastic component 60 be equivalent to fixture 70 turns an angle, thereby make the resiliency supported portion 62 of elastic component 60 that deformation occur, provide an elastic torsion in the rotation section 61 of elastic component 60, and then make limiting section 13 maintenances of keycap 10 and trigger unit 51 close contacts of key switch 50.
It should be noted that, when the key switch 50 of press-key structure 103 does not trigger, required pressing force when the trigger unit 51 that the elastic torsion that elastic component 60 puts on keycap 10 is less than key switch 50 triggers, thus avoid key switch 50 by false touch, key switch 50 can normally be worked.
The resiliency supported portion 62 of the elastic component 60 of above-mentioned press-key structure 103 is at key switch 50 not under triggering state, offset and elastic deformation occurs with fixture 70 phase strutting pieces 30, provide an elastic-restoring force in the rotation section 61 of elastic component 60, make trigger unit 51 close contacts of keycap 10 maintenances and key switch 50, thereby can avoid producing gap between keycap 10 and the trigger unit 51 of key switch 50, eliminate the idle stroke while pressing, while making to press described press-key structure 103, there is preferably feel.
Be appreciated that fixed support 20 can omit, now, strutting piece 30 is directly fixed on housing 101.Fixture 70 also can omit, and only needs the rotation section 61 of this elastic component 60 to be rotationally connected with this strutting piece 30, for example, convexes with the connecting portion with axis hole on strutting piece 30, and the rotation section 61 of elastic component 60 wears this axis hole.
In addition, those skilled in the art also can do other and change in spirit of the present invention, and certainly, the variation that these are done according to spirit of the present invention, all should be included in the present invention's scope required for protection.
